It was the screw end of a hose clamp coming off of that hose from the top rear of the valve cover. It was rubbing against my strut bar. I was just inspecting my hoses and so I checked that one and I heard that damn noise, so I was like aw ****ing hah? Just loosened the clamp, spun it around and re-tightened it. Problem solved.

 

Well that's strange. Although my strut bar does have a little wear mark in it from something rubbing on it.

 

my power steering hose used to rub against my neuspeed bar, then i relocated it a bit

 

That's the one I have. It's not straight across the top like the traditional strut bar, it fans out and I guess I just was not paying much attention when I replaced the hose on the valve cover after it tore. Oh well...at least it was nothing major.
